This is a Trial of MG1-E6E7 With Ad-E6E7 and Atezolizumab in Patients With HPV Associated Cancers

Summary

This is a Phase 1/1b open-label dose escalation trial of Ad/MG1-E6E7 and sequential treatment with atezolizumab in patients with HPV associated cancers. This study will consist of two arms. Both arms will dose escalate (MG1-E6E7) using a 3 + 3 design in Phase 1 to establish initial safety and the maximum tolerated dose (MTD) / maximum feasible dose (MFD). * Arm 1 - intravenous (IV) administration of MG1-E6E7 following intramuscular (IM) AD-E6E7 priming and subsequent treatment with IV atezolizumab. * Arm 2 - intratumoral (IT) and IV injection of MG1-E6E7 following (IM) Ad-E6E7 priming and subsequent treatment with IV atezolizumab. In the Phase 1b expansion for each arm, additional patients will be enrolled at the MTD as determined in Phase 1 in order to more thoroughly explore immune response, pharmacokinetics/dynamics, and safety for the patient populations with Cervical cancer, HPV positive (HPV+) Oropharyngeal cancer (Phase 1B, Arm 1, Cohorts A and B respectively) and HPV+ tumors with injectable lesions (Phase 1B, Arm 2, Cohort 3).
